Sandra, I see your post was a few months ago but I hope you check in from time to time. I have a little info on the Alexander MacRae you mention, married to Isabella Gibson in Parish of Nigg in 1814. Alexander died Feb 24, 1868 in Grand Anse, Richmond County, Cape Breton, NS and Isabella died there Feb 22, 1876. I have a list of kids, Donald, born 1816 Scotland; Alexander (no date); Isabella 1820 (died March 8, 1848 in NS); William 1821; Christy 1823; George 1830 and Philip 1833. My line seems to have sprung from William though I'm not entirely sure of that as my info is sparse. I'd love to hear from you.
